Issue 91

The Smart Export Guarantee (SEG) is an obligation set by the government for licensed electricity Suppliers to offer a tariff and make payment to small-scale low-carbon generators for exported electricity. The SEG came into force on 1 January 2020 and has introduced the need to register and settle export MPANs (Meter Point Administration Number), in accordance with the Balancing and Settlement Code (BSC) arrangements, for generators with capacity up to 5MW. For these smaller scale exports sites there is no established market and therefore the arrangements for Non Half Hourly (NHH) sites introduced by BSC Modification P081 ‘Removal of the Requirement for Half Hourly Metering on Third Party Generators at Domestic Premises’ have not been fully tested.

These arrangements are described in BSC Procedure (BSCP) 504 ‘Non Half Hourly Data Collection for SVA Metering Systems Registered in SMRS’ and BSCP514 ‘SVA Meter Operations for Metering Systems Registered in SMRS’. There are a number of scenarios arising which question whether these existing processes established for the import market are fit for purpose for the export market and for the use of shared smart Meters.

Issue 91 was raised by EDF on 5 November 2020.

The first Issue 91 Workgroup meeting was held on 8 December 2020. The Workgroup considered the background to Issue 91, reviewed and agreed the issues which had been identified and considered the next steps.

The second Issue 91 Workgroup meeting was held on 3 February 2021. The Workgroup reviewed relevant sections of BSCP514 ‘SVA Meter Operations for Metering Systems Registered in SMRS’  to identify any potential changes required for SEG sites.

The third Issue 91 Workgroup meeting was held on 2 July 2021. The Workgroup reviewed relevant sections of BSCP504 ‘Non Half Hourly Data Collection for SVA Metering Systems Registered in SMRS’ to identify any potential changes required for SEG sites.
